In a particular breed of cattle, a black coat is dominant over a red coat. If a cow with a red coat is crossed with a black bull that is heterozygous for coat color, what percentage of their offspring would you expect to be black?
25
50
75
100
1. B
2. B
3. C
4. A
5. D
6. D
7. C
8. Alleles
9. Mitosis
10. Meiosis
11. Incomplete dominance
12. Chromosomes
13. Reproduce
Do 14-16 on your own.
Hope this helped
Thanks Hi, I Got 100%!
12 is DNA but the rest is right
75%
Are they right
Is hi right
(My answers have ** beside them. If I get any wrong, I'm so sorry!)
1) A dog is trained to sit and shake hands. These traits are most likely
A. Inherited
B. Not inherited**
C. Not acquired
D. Innate
====================
2) In a particular breed of cattle, a black coat is dominant over a red coat. If a cow with a red coat is crossed with a black bull that is heterozygous for coat color, what percentage of their offspring would you expect to be black?
A. 25%
B. 50%
C. 75%** (not good at punnet squares and such please don't blame me if you get the incorrect answer.)
D. 100%
====================
3) A cow that is heterozygous for the black coat allele is crossed with a bull that is homozygous for the red coat allele. Which of the following Punnett squares represents this cross?
A. B B
b Bb Bb
b Bb Bb
B. B b
B BB Bb
b Bb bb
C. B b**
b Bb bb
b Bb bb
D. B b
B BB Bb
B BB Bb
==============
4) What is a mutation?
(lazy to write all the answers from here I'm just writing the one that I think is the answer.)
A. A mutation is a permanent change in the order of bases in DNA.**
================================
5) In humans, having dimples is a dominant trait. In order for a child to have dimples
D. at least one parent must have dimples and pass on the dominant allele.**
===================
6) A scientist is studying a plant species in which flower color genes are codominant. The scientist crosses a plant with red flowers and a plant with white flowers. The offspring will most likely have
D. red flowers with white patches**
===========================
7) In order for a child to inherit a recessive genetic disease, like sickle cell anemia, healthy parents must both
C. be carriers of the mutated gene that causes the disease.**
==================
For 8 through 13 there should be a glossary in your lesson! Do 14 and 15 by yourself. Feel free to check my work. ^^
-Sincerely,
OH BOY
It’s dna for 12
@Abbie lol just accept the answers and use them. If you would've liked an explanation than go back to previous lessons.
i dont understand i have a 16 question test but its not set up like they are saying!!! is the lesson called "introduction to genetics unit test"?????
HELP PLEASE
i think they switched it up on us
OH BOY has the 99% 😂Real No Clickbait😂99% Seal of Approval! There was one question wrong. which was two which, in my case, turned out to be B, 50%. Everything else is 100% correct!
- 💯% 😂Real No Clickbait😂💯%
1.b
2.b
3.c
4.a
5.d
6.d
7.c
the rest you have do by yourself because my teacher has not reviewed the answers yet, but just in case here's what I put
8.alleles
9.mitosis
10.meiosis
11.incomplete dominance
12.DNA
13. reproduce
14. during DNA replication, if errors are not fixed on time, a mistake when DNA is copied, as a result of something environmental. some mutations can cause albinism or cancer
15.durring sexual reproduction, the children are not identical to their parents
16. during asexual reproduction, the children are identical to their parents
Thanks for posting those yoe a life saver
Yes, wish people would learn to type the question and answers in word form so this wouldn't be such a problem.
i’m gonna type the answers but i have to do the typing answers first.
For science tests, in particular, do the questions switch around for everyone? Or does it stay exactly in the same place as everyone else? I'm asking this because in a lot of my Math tests they switch around the answers.
Your confused friend,
OH BOY
Hi also has the 99% 😂Real No Clickbait😂99% Seal of Approval! There is no Chromosomes option, which is incorrect. You also are not allowed to use capitals but who cares about that last part?
Can you do a Punnett square?
